BACKGROUND: Opportunistic infections due to Candida species occur frequently in cancer patients because of their inherent immunosuppression. The aim of the present study was to investigate the epidemiology of yeast species from the oral cavity of patients during treatment for oncological and haematological malignancies. METHODS: MALDI-TOF was performed to identify yeasts isolated from the oral cavity of 350 cancer patients. Moreover, antifungal susceptibility testing was performed in according to CLSI guidelines (M27-A3)...

INTRODUCTION: Chronic Lymphocytic Leukemia (CLL/SLL) is the most common adult leukemia in Western countries. Although it is mostly an indolent disease it is still incurable and with limited knowledge in relation to its etiology. We aim to confirm and quantify established risk factors for CLL/SLL using a multi-center epidemiological population-based case-control study on CLL/SLL as well as to explore new exposures inconclusively associated with CLL/SLL METHODS: Using the framework provided by the large MCC-Spain case-control study, we explored established and suggested risk factors associated with CLL/SLL using data collected through a face-to-face interview...

We conducted a surveillance epidemiology and end results (SEER)-based analysis to describe the incidence and characteristics of second primary acute lymphoblastic leukemia (sALL) among adults (≥18 years) with a history of primary malignancies (1M). Standardized incidence ratios (SIRs) of sALL cases were calculated by site and 1M stage. We also evaluated the differences in 5-year sALL survival by age, site, and extent of 1M, latency of sALL after 1M, and evidence of underlying racial/ethnic disparity. We identified 10,956 patients with de-novo/primary acute lymphoblastic leukemia (1ALL) and 772 with sALL...

Objective: To characterize the disease burden among survivors of those cancers having the highest incidence in the US. Methods: Adult (≥18 years) survivors of the 11 most frequently diagnosed cancers were identified from publically available data sources, including the Surveillance Epidemiology and End Results 9 1973-2012, National Health Interview Survey 2013, and the Medical Expenditure Panel Survey 2011. Chi-square tests and one-way analyses of variance were utilized to assess differences between cancer survivors and non-cancer controls in behavioral characteristics, symptoms and functions, preventative screenings, and health care costs...

Introduction: African Americans experience the highest burden of cancer incidence and mortality in the United States and have been persistently less likely to receive interventional care, even when such care has been proven superior to conservative management by randomized controlled trials. The presence of disparities in access to radiation therapy (RT) for African American cancer patients has rarely been examined in an expansive fashion. Methods and materials: An extensive literature search was performed using the PubMed database to examine studies investigating disparities in RT access for African Americans...

INTRODUCTION: The adolescent and young adult (AYA) age group (15-39 years) bears distinct characteristics in terms of cancer biology, long-term health and treatment-related complications and psychosocial aspects. The overall scenario of cancer including hematological malignancies (HMs) is largely unknown in Bangladesh, where a significant proportion of people (44% of total population) belong to AYA age group. This study aims to describe the patterns of HM among AYA in the context of Bangladesh METHODS: Two previously published datasets (on hematological malignancies and childhood and adolescent cancer) were merged to construct a comprehensive dataset focusing exclusively on HMs in AYA age group...

Diarrheagenic Escherichia coli (DEC) pathotypes with differing epidemiology and clinical features, are known causes of disease with worldwide occurrence. At a major cancer center in the U.S., we studied patients with cancer and diarrhea for whom a GI Biofire FilmArray multiplex GI panel (BFM) was performed. An enteropathogen was identified in 382 of 2017 (19%) samples distributed across 311 patients. Of these, 60/311(19%) were positive for DEC. Patients receiving hematopoietic stem cell transplants (HSCT) 29/60 (48%) or with a hematologic malignancy 17/60 (28%) accounted for the majority of DEC cases...

INTRODUCTION: Venous thromboembolism (VTE) is an important cause of morbidity and mortality in cancer patients, however the risk of VTE differs according to cancer type. Hematological cancers have varying phenotypes. Incidence rates (IR) of VTE in different hematological cancer types have not been investigated in a cancer-exposed subset of the general population. METHODS: In a population-based cohort, we estimated incidence rates of VTE among patients with six subtypes of hematological cancer and among age and sex matched reference subjects...

Fever may be the only clinical symptom at the onset of infection in neutropenic cancer patients undergoing myelosuppressive chemotherapy. A prompt and evidence-based diagnostic and therapeutic approach is mandatory. A systematic search of current literature was conducted, including only full papers and excluding allogeneic hematopoietic stem cell transplant recipients. Recommendations for diagnosis and therapy were developed by an expert panel and approved after plenary discussion by the AGIHO. Randomized clinical trials were mainly available for therapeutic decisions, and new diagnostic procedures have been introduced into clinical practice in the past decade...

INTRODUCTION: Testicular seminoma affects relatively young men with excellent survival outcomes. There has been increasing concern that radiotherapy (RT) leads to secondary malignant neoplasms (SMNs) and subsequent mortality. We evaluated the effect of RT on incidence of SMNs and quantified cancer-related mortality and other causes of death for patients with stage I and II testicular seminoma. MATERIAL AND METHODS: A national sample of men (1988-2013) diagnosed with stage IA/IB/IS/IIA/IIB/IIC testicular seminomas from Surveillance, Epidemiology, and End Results were evaluated...

BACKGROUND: With the improving outcomes of patients with follicular lymphoma (FL), it is imperative to focus on survivorship issues, including the development of second primary malignancies (SPMs). We used a large US database to measure the risk of SPMs among FL survivors. MATERIALS AND METHODS: We used the Surveillance, Epidemiology, and End Results-13 registry to identify FL patients from 1992 to 2011. We calculated the risk of SPMs, developing ≥ 6 months after diagnosis, using the standardized incidence ratio (SIR) and absolute excess risk...

BACKGROUND: Second hematologic cancers in patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL) are well documented and include Hodgkin lymphoma, therapy-related acute myeloid leukemia/myelodysplastic syndromes, and transformation to diffuse large B-cell lymphoma. Although cutaneous T-cell lymphoma (CTCL) has been reported in patients with CLL, the incidence and comparison to expected rates are unknown. We evaluated the incidence of CTCL among patients with CLL or other non-Hodgkin lymphoma (NHL) subtypes using data from the Surveillance, Epidemiology, and End Results (SEER) Program...

Epidemiological studies have associated the exposure to permethrin and malathion with increased risk of leukemia and lymphoma. The aim of this study was to evaluate whether in vitro exposure to permethrin and malathion induces aberrations in genes involved in the etiology of these hematological malignancies. Genetic abnormalities in the IGH, KMT2A (MLL), ETV6 and RUNX1 genes, and aneuploidy induced by the in vitro exposure to permethrin and malathion (200μM, 24h), were analyzed by FISH in peripheral blood mononuclear cells (PBMCs)...

A major cause of morbidity and mortality in patients with cancer is infection. Since the introduction of the Haemophilus influenzae type b (Hib) vaccine in the United States in the 1990s, invasive H influenzae infection has become less common. We report on 5 patients with cancer and invasive H influenzae infection. A literature review was also performed of the dominant Haemophilus subtype and the clinical features associated with the infection and concomitant cancer. Of the 17 cases found in the literature, had hematological malignancies and 1 case each had thymoma, schwannoma, teratoma, and pancreatic, Merkel cell, pharyngeal, laryngeal, and rectal carcinomas...

REVIEW
Kenneth V I Rolston
Solid tumors are much more common than hematologic malignancies. Although severe and prolonged neutropenia is uncommon, several factors increase the risk of infection in patients with solid tumors, and the presence of multiple risk factors in the same patient is not uncommon. These include obstruction (most often caused by progression of the tumor), disruption of natural anatomic barriers such as the skin and mucosal surfaces, and treatment-related factors such as chemotherapy, radiation, diagnostic and/or therapeutic surgical procedures, and the increasing use of medical devices such as various catheters, stents, and prostheses...

184 Background: End-of-life (EOL) care for persons with hematologic malignancies is variable and often involves high-intensity services at death approaches, which may not reflect patient or family preferences. We characterized healthcare utilization and associated costs in the last 30 days of life among subjects with leukemia or lymphoma to better understand patterns of care in this population. METHODS: We linked enrollment and claims records from two regional commercial insurers to Surveillance, Epidemiology, and End Results (SEER) records for patients diagnosed with leukemia or lymphoma in Western Washington state between January 1, 2007 and December 31, 2015...
